ABSTRACT
Introdução: os enxaguantes bucais clareadores tem sido muito utilizados, porém sua eficiência e efeitos colaterais trazem questionamentos. Objetivo: este ensaio clínico teve como objetivo avaliar se o enxaguante bucal clareador, contendo peróxido de hidrogênio a 1,5%, apresenta ação clareadora e se há algum efeito secundário na cavidade bucal. Metodologia: foram selecionados 10 voluntários com idade média de 21,5 anos, submetidos a avaliação da cor dos dentes com auxílio do espectrômetro em 3 momentos: inicial; com 15 e com 30 dias de uso do enxaguante. A avaliação dos efeitos colaterais foi realizada a partir da coleta de saliva estimulada em 4 momentos: antes e depois ao primeiro uso do produto, com 15 e com 30 dias, e realizadas as análises laboratoriais: fluxo salivar; pH; quantidade de Streptococcus mutans e de Lactobacillus. A normalidade dos dados foi verificada pelo teste de Shapiro-Wilk, comparação de cor pelo teste t dependente, comparação dos microrganismos pelos testes ANOVA de medidas repetida e Tukey. Resultados: as análises de cor dos dentes não evidenciaram nenhuma alteração significativa em nenhum dos tempos investigados. No fluxo salivar, pH e Lactobacillus não houveram alterações significativas. Na quantidade de Streptococcus mutans notou-se um aumento significativo quando comparado os valores após o primeiro uso e com 30 dias. Conclusão: a solução de enxague bucal contendo peróxido de hidrogênio a 1,5% não apresentou alteração significativa na coloração dos dentes e nenhum efeito colateral significativo na atividade cariogênica de acordo com os testes e períodos avaliados.
Introduction: whitening mouthwashes have been widely used, but their efficiency and side effects raise questions. Objective: this clinical trial aimed to assess whether the bleaching mouthwash, containing 1.5% hydrogen peroxide, has a bleaching action and whether there are any side effects in the oral cavity. Methods: 10 volunteers were selected, with a mean age of 21.5 years, who underwent tooth color evaluation with the aid of a spectrometer in 3 moments: initial; with 15 and 30 days of using the washes. The evaluation of side effects was performed from the collection of stimulated saliva in 4 moments: before and after the first use of the product, at 15 and 30 days, and laboratory analyzes were carried out: salivary flow; pH; the number of Streptococcus mutans and Lactobacillus. Normal distribution was verified with Shapiro-Wilk test, comparisons of color were performed with t-test, comparisons of the microorganisms were performed with repeated measures ANOVA and Tukey tests. Results: the analysis did not show any significant changes in any of the investigated times. There were no significant changes in the salivary flow, pH and Lactobacillus. The number of Streptococcus mutans, was noted a significant increase when comparing the values after the first use and with 30 days. Conclusion: the mouthwash containing 1.5% hydrogen peroxide was not shown any significant alterations in the color teeth. There were not significant collateral effects on the cariogenic activity according to the tests and periods evaluated.

Abstract The present study sought to evaluate the impact of quarantine resulting from the coronavirus disease 2019 (COVID-19) pandemic on dental appointments and patients' positions and concerns regarding their ongoing dental treatment. Patients from private dental clinics answered an online questionnaire anonymously regarding their treatment, availability and willingness to attend dental appointments, and concerns about contamination. Descriptive statistics of the responses were performed with percentages and responses were compared between sexes, regions, and other aspects using the chi-squared test. Five hundred ninety-five patients (412 females and 183 males; mean age: 38.21 years) answered the questionnaire. Most patients reported they were receiving dental treatment (orthodontics) and would attend to a dental appointment; meanwhile, those patients not receiving treatment would not attend or would visit only in the case of an emergency. Males reported to be calmer than females, who were more anxious and afraid; as such, males reported more willing to go a dental appointment while, in general, females were not worried about how quarantine could affect dental treatment. Patients actively undergoing treatment and orthodontic patients were more concerned about a delay in treatment. There was a significant association between feelings about the COVID-19 pandemic and the level of willingness to attend a dental appointment. The quarantine recommended due to the COVID-19 pandemic was shown to have an impact on dental appointments and the anxiety levels of patients, since there was a significant association between patients' feelings and their willingness to attend a dental appointment. Overall, patients undergoing dental treatment and orthodontics were more willing to attend an appointment and were more concerned about an increase in treatment duration.

Introduction: Class II malocclusions have several treatment protocols, and we are increasingly moving towards more conservative orthodontics, avoiding dental extractions whenever possible. A great alternative for treatment in standard II patients has been the use of mandibular protraction appliance, which promote correction of this malocclusion. In the article in question will be reported the use of the Twin Force Bite Corrector appliance in the correction of a unilateral class II. Objective: case report of malocclusion with mandibular propellant. Method: One-phase treatment with the use of a fixed orthodontic appliance associated with a fixed mandibular propulsion orthopedic appliance, Twin Force Bite Corrector (TFBC). Result and Conclusion: The treatment was able to promote the reduction of the overjet, obtaining a stable Class I molar and canine relationship with coincident midlines and the improvement of the soft tissue profile.
Introdução: As más oclusões de classe II apresentam diversos protocolos de tratamento, sendo que a cada dia mais estamos caminhando para uma ortodontia mais conservadora, fugindo sempre que possível de extrações dentárias. Uma ótima alternativa para o tratamento em pacientes padrão II tem sido o uso de propulsores mandibulares, que promovem uma correção dessa má oclusão. No artigo em questão, será relatado o uso do aparelho Twin Force Bite Corrector na correção de uma classe II unilateral. Objetivo: relato de caso de má oclusão com uso de propulsor mandibular. Método: tratamento em uma fase com a utilização de aparelho ortodôntico fixo associado a um aparelho ortopédico fixo de propulsão mandibular, Twin Force Bite Corrector (TFBC). Resultado e Conclusão: O tratamento foi capaz de promover a redução do overjet, obtenção de uma relação Classe I molar e canina estável com linhas médias coincidentes e a melhora do perfil do tecido mole.
